SH2-119

Sharpless 119 is an emission nebula. It is glowing orange due the hydrogen gas and blue due to the oxygen gas in the nebula being energized by the star BD +45 3216 embedded within. This star is much more massive than our Sun, and emits copious amounts of ultraviolet (UV) light that causes the gases to glow.

The image was generated with observations in Hydrogen A, Oxygen III and Sulphur II wavelengths combined into the visible Red/Green/Blue channels using the Hubble palette.
